Separating signal from noise
Perform digital debugging with portable oscilloscopes with customized application-specific integrated circuits (ASICs) that provide four times the vertical resolution and half the injection noise of other general-purpose oscilloscopes. Debugging with oscilloscopes reveals small signals outside of the noise and captures the slightest and rarest of signal burrs to troubleshoot designs and ensure product quality.
- Quadruple the vertical resolution with a 14-bit analog-to-digital converter (ADC).
- Viewing a file with 50 µVRMS The smaller signal of the background noise.
- Finds signal burrs at an update rate of 1.3 M waveforms/second.
- Capture longer time spans at full sample rate and 100 Mpts deep memory.
- Display up to 4 independent signals and control scaling individually.
- Isolate signals in seconds with area triggering - just draw a box on the screen.
- Use the Keysight Fault Hunter to characterize signals, find errors, and save them automatically.
- Perform advanced analysis using Fast Fourier Transforms, Histograms and Porter Plots.
Debugging designs with 4x resolution and 1/2 noise floor
Product quality is ensured by debugging with an oscilloscope that can see small signals beyond the noise.
7 in 1 Instrument
More than just an oscilloscope, the HD3 helps you save valuable bench space by supporting additional instrument integration to provide more functionality in the same footprint:
- Oscilloscopes with 2 or 4 analog channels
- Mixed-signal oscilloscope with the ability to add up to 16 digital channels
- Protocol Analyzer
- Frequency Response Analyzer (baud plot)
- 100 MHz Arbitrary Waveform Generator
- 3-Digit Voltmeter
- 8-Bit Counter with Totalizer

Probes for every application
Start using the probes that come standard with your HD3 oscilloscope immediately:
- Learn about the Keysight N2843A passive probe, which offers a 500 MHz bandwidth, 10:1 attenuation ratio, and high input impedance of 10 MΩ (standard input impedance per channel).
- Explore the mixed-signal oscilloscope (MSO) capabilities that come standard with the HD3. If you're already using a 16-bit digital channel MSO cable from YesTech, just plug it in.
Do you need additional features? YesTech offers a wide range of voltage, current and optical detection solutions for oscilloscopes.
